Old moen vestiage kitchen faucet with current low water pressure. how do we fix?

To Remove Moen Kitchen Faucet.
Regardless of the type of faucet being installed, there are a few basics steps everyone will follow.
First, shut off the water supply to the old faucet using valves typically located under the sink. Then remove those supply lines and the old faucet.
Before installing the new faucet, check the area around the sink and clean up any gunk or old caulk that you couldn't see before, Simons says.

clean airator

clevine336-

The design of a hand sprayer is meant to provide a higher pressure spray (the smaller outlet size means greater velocity in the water coming out of the sprayer head). That said, there could be something constricting the water flow in your faucet. If you unscrew the aerator on the end of the faucet do you get better pressure? Is the screen in the aerator clogged with sediment or mineral deposits? If this is the case you may have water requiring periodic cleaning of the aerator.

Hope this helps.

I have had the cartridge replaced in my moen single handle faucet with sprayer in the end and now it turns off by itself. Any suggestions on the problem

IS THIS A SHOWER ONLY? IF SO ,I WOULD REMOVE THE SHOWER HEAD FIRST THEN TURN YOUR WATER ON.THE HEAD JUST MIGHT NEED TO BE CLEANED AFTER 11 YEARS.

remove the device from faucet and look into it for a small screen is it clean.

If you contact Moen, they will send you a new cartridge, as well as tool to replace it. ( 1-800-buy-moen )
No charge.

I have moen kitchen faucet # 7560 and water pressure very low. What should I do? We check water flow in pipe it is ok. I changed cartridge as well as pipe nothing help. Please let me know. thanks

if the pressure is good with the head off then you can probably get a new head for it u shouldn't have to change the cartrige. it sounds like the head is clogged so plastic pieces in the head to help save water "water savers" it is hard to clean them i would try changing the head u should be able to find on for a moen, u buy for looks u buy it for life. take the old head with u when u go to buy a new one so they can match it up to the right one.if you can't find it and a lowes or home deptm try a plumbing supply house
